Answer:
x=2
Step-by-step explanation:
4x-6=6-2x
(add 2x and 6 to both sides)
6x=12
(divide by six)
x=2
Double Check:
4(2)-6=2
6-2(2)=2
4(2)-6=6-2(2)
Answer:
its either 3 or 4
Step-by-step explanation:
w = number of weeks
b(w) = number of books read after w weeks
====================================
b(w) = 12 translates to "after w weeks, Katy will have read 12 books" or put another way "Katy will have read 12 books after w weeks". The 'w' is a placeholder for some number
====================================
b(2) = 10 means "Katy has read 10 books after 2 weeks". We use the same basic idea talked about above, but we replace w with 2. At the same time, we use 10 instead of 12.
====================================
b(3) = f means "Katy has read f books after 3 weeks" or "after 3 weeks, Katy has read f books". Like w, the f is a placeholder for some number.
Answer:
C. a reflection in the y-axis
Step-by-step explanation:
The mapping statement for the transformation of the vertices of the triangle ABC is given as following:
A(0,2)→A'(0,2)
B(2,9)→B'(-2,9)
C(4,2)→C'(-4,2)
To find the correct transformation for the given statement.
Solution:
From the given statements, the general transformation statement for the the vertices of the triangle can be given as:
The above transformation shows a reflection in the y-axis as the transformation in y-axis changes the sign of the x-coordinate of the point.
Ratios are equivalent when that can be reduced or multiplied to be the same number.
Ex) 1:4 is the same as 2:8 or 4:16
10:20 is the same as 8:16 or 1:2
They are not equivalent if you can’t do this
